U.S. Marines prepare to leave upon the end of operations for the Marines and British combat troops in Helmand on Oct. 27, 2014.
A fleet of planes and helicopters airlifted the last U.S. and British forces from a key base in southern Afghanistan on Monday, a day after the international coalition closed the massive facility and handed it over to the Afghan military.
The troops' withdrawal and base closure in the province of Helmand is one of the largest operations in the winding down of the international combat mission in Afghanistan, 13 years after the toppling of the radical, Islamist Taliban regime.

Staff Sergeant Kenneth Oswood, of Romney, West Virginia, is one of the few members of the squadron who participated in both the Iraq withdrawal and Monday's Helmand airlift.
"It's a lot different this time .... Closing out Iraq, when we got there, we were told there hadn't been a shot fired in anger at us in years. And then you come here and they are still shooting at us," Oswood said.
"It's almost like it's not over here, and we're just kind of handing it over to someone else to fight."
